When Roswaal happily tells the story of how his romance with Echidna began 400 years ago, Beatrice rebukes him for casually calling it a "romance." Ryuzu interrupts to comment that Echidna saved her, as well. The one thing these three very different people share is their gratitude toward Echidna. But their days spent in both amicable and argumentative conversation about Echidna are brought to an end by one man's arrival.

No podemos vencerlo peleando.

Você não poderá
ganhar dele só lutando.
Его нельзя одолеть в бою. 
Вот зачем нужно Святилище.
